SEWING-MACHINE ATTACHMENT.

Specification of Letters Patent.

Patented Mar. 14, 1911.

Application filed January 28, 1910. Serial No. 540,491.

To all whom it may concern:

Be it known that I, BERTHA S. ALsor, a citizen of the United States,residing at Los Angeles, in the State of California, have i11- vented acertain new and useful Improvement in Sewing-Machine Attachments, ofwhich the following is a full, clear, and exact description.

This invention is a sewing machine attachment, the principal object ofwhich is to facilitate the sewing of braid onto cloth, although theattachment is also useful in the application of ornamental linestitching to fabrics.

Heretofore an operator using a sewing machine for sewing on braid orapplying line stitching has been obliged to lift the presser foot of themachine frequently, and especially when making sharp turns of the fabricbeneath the presser foot. The use of my invention hereinafter describedrenders this lifting of the presser foot unnecessary, and makes itpossible for the operator to continuously run the machine to turn thecloth as sharply or as frequently as desired beneath the presser footand without the lifting of the same.

The invention consists of a disk applied to the under face of thepresser foot and pivoted thereto on a vertical axis, so as to be freelyrotatable, the said disk having a hole through it which is coaxial withthe vertically reciprocating needle of the machine, whereby said needlemay pass through this hole and through the presser foot.

The invention also consists in the above mentioned construction whensaid disk has through it a substantially horizontal passage or braidguide; which intersects and crosses said needle opening and is slottedor open through the bottom of the disk at one side from its intersectionwith said needle hole to the periphery of the disk, access being had tosaid passage through a parallel slot extending across the top of thedisk at one side of said needle hole and adapted, when in workingposition, to be closed by the presser foot immediately above it, or tobe opened when swung transversely out of working position beneath thepresser foot.

It also consists in certain other character istics of construct-ionshown and hereinafter described and definitely pointed out in theclaims.

The accompanying drawing illustrates the lnvention in what 1s nowconsidered the .best embodiment thereof; and the new and novel featuresthereof are set out in the appended claims.

In this drawing, Figure 1 is a perspective view of a presser-footattachment of avsew ing machine having the invention applied thereto.Fig. 2 is a plan view partly in section on the line 2, 2 of Fig. 4:, ofthe disk detached from the .prcsser-foot and partly in section throughits hollow spindle immediately above the disk surface. Fig. 3 is aninverted or bottom plan of the same. Fig. 4 is a vertical transversesection through the presser-foot and guide disk on the line 4-4 ofFig. 1. Fig. 5 is an elevation of the oppo site side of the disk butshowing the presserfoot in transverse section as indicated by the arrows5, 5, on Fig. 1. Fig. 6 is an end elevation of the presser-foot andguide disk as viewed from the left of Fig. 1; and Fig. 7 is a verticalcentral section through the presser-foot and guide disk in the planegenerally indicated by line 7-7 of Fig. 1, with the cord slot turnedparallel to the front edge of the presser-foot.

The presser-foot A is formed at its upper end suitable for connection inany sewing machine with which it is to be used. The disk B lies againstthe under face of the horizontal part of the presser-foot, and ispivoted thereon on a vertical axis. Preferably it has a shortcylindrical stud Z2 which goes vertically upward through a eylindricalhole in the horizontal part of the presser foot and has its upper endupset slightly to hold it in place. A cylindrical hole 6' passesvertically and axially through this disk and its stud, which hole iscoaxial with the needle of the machine, so that the needle may passthrough it in its vertical reciprocatory movements. Preferably, thelower face of this disk is slightly crowned. It is this lower face ofthe disk which rests upon the fabric being sewed when the device is inuse. A braid guide C passes horizontally through the disk in asubstantially diametrical direction, so as to intersect and cross thevertical needle opening Z). Vhen in operation, the braid to be sewed ona piece of cloth goes through this transverse opening. In order tofacilitate the thread ing of the braid into this opening there is a slot0 extending across the top of the disk and communicating at its lowerend with this braid guide. When the disk is in the position in which itwill most commonly stand in use, the braid guide extends in a directionsubstantially parallel with the length of'the horizontal part of thepressere "foot. When the disk is in this position, the

' presser-foot overhangs the slot 0, and thereby prevents the braid fromaccidentally being drawn out of its guide through this slot. If,however,-the disk be turned at right angles to its common position, asstated, the

said slot 0 will be so exposed as to admit the,

the braid, it will slip under and in contact with the lower face of saiddisk. The disk, 'd

as the cloth is turned, may be slightly turned, but it can be easilydrawn back to proper working position by the operator through her holdupon the braid. If the attachment is to be used for fancy linestitching, of course no braid is threaded through the disk, and, infact, no guide for such braid is necessary. Y r

Having described my invent-ion, I claim:

1. In a sewing machine attachment in combination a resser-foot, and adisk pivxoted on a vertical axis to the lower face of the horizontalpart of said presser-foot, there being through said disk and presserfoota vertical hole which is coaxial with said disk and is adapted to beheld directly beneath the sewing machine needle whereby the latter maypass through it,'said disk having a horizontal braid guide through itwhich intersects said vertical hole.

2. In a sewing machine attachment in combination a presser-foot, and adisk pivoted on a vertical axis to the lower face of the horizontal partof said presser-foot, there being through said disk and presserfoot avertical hole which is coaxial with I said disk and is adapted to beheld directly beneath the sewing machine needle whereby the latter maypass through it, said disk having a horizontal braid guide through itwhich intersects said vertical hole, and there being through the top ofsaid disk and at one side of the axial hole a transverse slot whichleads to said braid guide-way.

3. In a sewing machine attachment in combination a presser-foot, and adisk pivoted on a vertical axis to the lower face of the horizontal partof said presser-foot,- there being through said disk and presserfoot avertical hole which is coaxial with said disk and is adapted to be helddirectly beneath the sewing machine needle whereby the latter may passthrough it, said disk having a horizontal braid guide through it whichintersects said vertical hole, and there being through the top of saiddisk and at one side of the axial hole a transverse slot which leads tosaid braid guide-Way, said slot being in a part of the disk whichnormally lies beneath the horizontal part of the presser-foot, but whichis adapted to be operatively uncovered by the turning of said 4. In asewing machine attachment in combination a presser-foot, and a diskpivoted ,on a vertical axis to the lower face of the horizontal part ofsaid presser-f0ot,- there being through said disk and presserfoot avertical hole which is coaxial with said disk and is adapted to be helddirectly beneath the sewing machine needle whereby the latter may passthrough it, said disk having a horizontal braid guide-through it whichintersects said vertical hole and there being through the top of saiddisk and at one side of the axial hole a transverse slot which leads tosaid braid guide-way, said slot being in a part of the disk which isnormally covered by the resser-foot, and the presser-foot having anupwardly beveled lower surface which, when the disk is turned BERTHA S.ALSOP.
